With the acceleration of urbanization, human needs to connect with the nature and experience the aesthetic qualities such as landscape aesthetic, fresh air, topographic diversity and green infrastructures. Hence, landscape aesthetic quality is regarded as a valuable source of conservation. The purpose of landscape visual quality assessment is to identify the criteria for preserving and rehabilitating the aesthetic value based on them. In order to quantify the aesthetic value, after bringing the literature review and considering the characteristics of the study area, the effective criteria on the aesthetic value were determined, mapped and then standardized. In the next step, areas with aesthetic value were determined using the weighted linear combination method. Finally, areas with varying degrees of suitability of aesthetic were identified. According to the results, the regions with the highest aesthetics value and the area of 40.64 Km 2 had the minimum area, while those with the low aesthetic value and the area of 477.65 Km 2 had the maximum area. The results of this study can be useful for decision makers to improve the landscape management and quality.

Invasive plant control is a significant challenge for natural resources management. Rosa persica (Michx ex. Juss.) is one of the invasive species in Iran. It has been rapidly expanded to the areas where it has introduced. In the present study, we evaluated the effects of five treatments: 1) control, 2) fire, 3) cutting, 3) tilling, 4) chemical techniques (glyphsate application) in controlling the expansion of Rosa persica in a degraded rangeland plant community ( Rosa persica dominant type) in Markazi province. An experiment was arranged in split plots based on a completely randomized block design with four replications for three consecutive years. We found that the combined methods have played a more effective roles in controlling the Rosa persica and among these methods; fire combined with chemical techniques appeared to be a better option for reducing the abundance of Rosa persica . Also, fire combined with the mechanical removal of the above-ground and fire combined with the mechanical removal of the root reduced population size of Rosa persica , as comapred with the control, however, no significant difference (P<0.05) was found between the two methods. Thus, because of the disturbance in the soil, as a result of the mechanical removal of root, we recommend the use of fire combined with cutting instead of tilling to reduced Rosa persica .

Landfill location is one of the most important aspects of municipal solid waste management. Selecting a suitable solid waste landfill site can prevent adverse ecological and socioeconomic effects. Therefore, the aim of this paper was to determine the solid waste landfill site selection problem in Bushehr city, according to some criteria including the considered land use, distance from surface and underground water, soil texture, precipitation, wind direction, geology, slope and distance from the fault, distance from the residential areas and distance from roads, and distance from the industrial parts and facilities . For this purpose, calculated criteria were weighted using the analytical hierarchy process (AHP). A geographic information system (GIS) was then used to manipulate and present the spatial data. The candidate sites by aggregation based on the criteria weighted by the weighted linear combination (WLC) method were determined and the candidate sites were divided to unsuitable and good landfill areas. In the good landfill area, with the least time and investment, there was the possibility of developing a solid waste. By considering the minimum required landfill area for 10, 20, 50 and 100 years, the candidate sites were prioritized. The results of the site suitability assessment showed that the site E in Bushehr city was the suitable area for locating the disposal of solid wastes, covering an area of 3738 ha, 3.7% of the total area.

This study aimed to investigate the effects of the fire products treatments (heat, smoke and ash) on the density, species diversity, growth form and the life form of the soil seed bank in the semi-steppe rangelands of the Karsanak region in Chaharmahal and Bakhtiari Province. For this purpose, soil samples were collected from the studied region and fire products treatments were applied to them. Five treatments, including two treatments of heat shock (60 and 80 °C), one treatment of ash (30 minutes) and control (without any treatment), were tested. Totally, seeds of 21 species from 15 plant families of the soil seed bank samples cultured in greenhouse, were germinated. The results showed that the heat treatment at 80 °C with an average seedling number of 706 per m 2 had the highest density in comparison with the control. Also, ash significantly increased the diversity and richness of the cultured samples. Most of the fire products treatments increased the share of the annual vegetative form (annual forb and annual grass). According to the results, it can be concluded that fire products effects on plant species are very important in recognizing and analyzing the responses of species in the irritability of the germinating seeds. Also, based on this information, we can predict the changes in the vegetation after the fire, which can be used in the management of natural ecosystems.

In the current study, conservation strategies were employed for the spatial analysis of forest fragmentation and field assessment approaches in a forest landscape of Central Zagros, in the western part of Isfahan province, Iran. Vegetation and soil properties were accordingly studied in 15 forest sites with various densities including dense, semi-sparse and sparse-forests with 839.2 km 2 . In the Landscape Function Analysis (LFA) method, 11soil surface indicators were assessed from each patch and inter-patch zones along the established transects to obtain three functional indices including soil-stability, infiltration and nutrient-cycling. In the health method, assessors rated 17 indicators to evaluate three functional attributes of ecosystems including soil and site-stability, biotic-integrity and hydrologic-function. Land use map of the study area was produced using Landsat OLI (2016) to measure the spatial distribution of fragmentation. The results of LFA showed that the stability and nutrient-cycling indices of the dense-forest sites were 72.4 and 57.9%, respectively, which were significantly higher than those in other lands (p < 0.05). According to the health results, soil surface loss, invasive plants and soil surface resistance to erosion were the most important factors influencing the health of the sites. The values of normalized fragmentation in dense-forest and sparse-forest areas were 54% and 96.3%, respectively. According to the obtained results, the combined field-based and remotely-sensed approaches applied in this research could be used to assess the functionality of Zagros forests.
在本研究中，采用保护策略对伊朗伊斯法罕省西部中部扎格罗斯的森林景观进行了森林破碎化的空间分析和实地评估方法。在839.2 km2的密林、半疏林和疏林等不同密度的15个样地进行了植被和土壤性质的研究。在景观功能分析(Landscape Function Analysis, LFA)方法中，沿着建立的样带对每个斑块和斑块间带进行11项土壤表面指标评价，得到土壤稳定性、入渗和养分循环3项功能指标。在健康法中，评估者评定了17个指标来评价生态系统的3个功能属性，包括土壤和场地稳定性、生物完整性和水文功能。利用Landsat OLI(2016)制作研究区土地利用图，测量破碎化的空间分布。结果表明:密林立地土壤稳定性和养分循环指数分别为72.4和57.9%，显著高于其他地(p < 0.05);从健康结果来看，土壤表面流失、入侵植物和土壤表面抗侵蚀能力是影响站点健康的最重要因素。密林和疏林区归一化破碎度分别为54%和96.3%。根据所获得的结果，本研究采用的实地和遥感相结合的方法可以用于评估扎格罗斯森林的功能。
